/**
 * =========================
 * A few (wise) words
 *
 * For consistency amongst our themes, we have put as much of the theme behaviour (both logical and stylistic)
 * in components (the `components` directory). This includes the "classic" theme files like `archive.php`, `single.php`,
 * `header.php`, or `sidebar.php`.
 * Do no worry. You can still have those files in a theme, or a child theme. It will automagically work!
 *
 * We prefer not to use those files if the theme design allows us to stick to the markup patterns common to our themes,
 * available in our components.
 * This will make for more solid themes, faster update cycles and faster development for new themes.
 *
 * Now, let the show begin!
 * Oh snap... it already began :)
